sqplot: Plot of Non-constant Solar Quiet Daily Variation

Description

This function visualizes the estimated non-constant solar quiet daily variation of each station. Users would define how many graphs to be put into one page, The default set is 2 graphs per page.

Usage

sqplot(x, start = NULL, end = NULL, n.station = NULL, graphs.per.page = 2, station.names = NULL, Title = NULL, ...)

Arguments

x

estimation of solar quite variations from SQ

start

start date of records for magnetic activities. See examples

end

end date of records for magnetic activities. See examples

n.station

number of studied stations

graphs.per.page

how many graphs combined in one plot page. Default number is 2

station.names

NULL (indicating no station names) or a vector strings for station names.

Title

title of sqplot

...

additional arguments

Details

This function is used to visualize estimated Sq variation. Specifying the names of each stations would add station names at y-axis.
